At 6 a.m., Ken and Japheth left Park P and drove towards Park Q at average speeds of 97 km/h and 60 km/h respectively. Upon reaching Park Q, Ken rested for 2 hours. He then headed back for Park P at an average speed of 97 km/h along the same route. Ken and Japheth met each other on their way at 12 noon.
- How far had Ken covered when he met Japheth on the way?
- How far apart were the two parks?
(a)
Time taken by Japheth = 6 h
Time taken by Ken = 6 - 2 = 4 h
Distance covered by Ken when he met Japheth
= 4 x 97
= 388 km
(b)
Distance travelled by Japheth
= 6 x 60
= 360 km
Distance of the two parks
= (388 + 360) ÷ 2
= 748 ÷ 2
= 374 km
Answer(s): (a) 388 km; (b) 374 km
